This invention is an improvement in strawstacking machines or attachments for harvesters, and its object is to provide an endless belt carrier or carriers which can be transported conveniently, can be elevated to deliver the straw at different heights as the stack is built, and can be conveniently folded into a small compass for transportation, and it consistsin a pair of belt-carriers and a novel supporting and connecting device therefor and in certain novel details of construction thereof, as willbe more clearly understood from the following description and claims.

Referring to the drawings by letter A designates a frame composed of uprights a a, connected by transverse pieces a a.

B designates a frame consisting of side pieces I) Z), connected by transverse pieces Z) and telescoping with frame A, the two frames thus constituting an extensible or adjustable support for the carrier. Frame Bis raised or lowered in frame A by means of a rope or chain 0, attached to the lower end of frame B, running up over a pulley attached to a top piece and then down to a drum or shaft 0, supported in bearings attached to frame A, as indicated in the drawings.

D and E designate short horizontal shafts arranged one below the other and j ournaled in one side piece I) of frameB and in a bracketiron B, attached to the outer side thereof, as shown. (Z c are pulleys on the said shafts between the bracket and side pieces, and d is a belt connection between said pulleys. D and E are clutchblocks on the inner ends of said shafts, respectively, which blocks have Serial No. 335,666- (No model.)

diametrical slots 6 in their outer faces, as shown.

F designates a metallic bracket attached to the inside face of piece I) and extending over blocks D E, and in the vertical portion of this bracket directly opposite said blocks are oppositely-bearing open slots F F which incline upwardly and outwardly, the upper slot F opening toward the receiving end of the machine and slot F? toward the delivery end. On the opposite piece b of frame Bis secured a metallic plate f, which has similar slots f f in it, corresponding to slots F F and directly opposite the latter.

G designates the receiving-section of the conveyer, formed of side pieces G G,co11- nected by a transverse partition g.

II and I are transverse shafts at the opposite ends of the section and journaled in metallic flanged collars 7t 1', attached to the side pieces as shown, or in other suitable bearings, and on these shafts between the frames are suitable belt-pulleys, and over them runs an endless oonveyer-belt J of ordinary construction. The collars h project from the side pieces G, and they rest in bearing-plates 7c is. which, as shown in the drawings, are attached to the upper ends of uprights K K, but may be attached to the thrasher or to any suitable support to uphold the rear end of the section. The collars 2' i are slipped into notches F f of bracket F and plate f, and thus uphold the front end of section G, as indicated. The end of shaft I at the side adjoining bracket F projects through its collar, and on it is a diametrically-arranged bolt or pin 1', which engages the slot 6 in block D, so that shafts D and I are interlocked.

L designates the upper section of the conveyer, similar to section G in construction, excepting that the lower ends of its side pieces L L are rounded, as indicated.

M designates a shaft journaled in collars N N, attached to the lower ends of the side 7 pieces of section L, and m is a shaft journaled in the side pieces at the upper end of the section. Said shafts'bear conveyer-belt pulleys, and an ordinary endless belt j runs thereover. The collars N N are engaged with and rest in notches F f of bracket 1 and plate f, as shown, thus supporting the lower section end of section L, and the end of shaft M, adjoining bracket F, is provided with a transverse pin to engage slot 6 of block E, thus interlocking shaftsE and M. The outer end of section L is unsupported, but. is upheld by ropes or chains 0 0, attached to its side pieces and running up over sheave-pulleys 0 0, attached to the upper ends of pieces I) b, and then down to a drum or shaft P, journaled in bearings attached to frame A, as indicated in the drawings.

The power is applied to shaft I-I. Belt J transmits motion from this shaft to shaft I, the latter to shaft D, which, through belt d, drives shaft E, and the latter shaft M, by which belt j is operated.

It will be observed that the sections can be elevated or lowered with frame B to adjust the delivery end of the carrier as the stack is built; also,that the uppersection can be adjusted independently of the other. Again it will be observed that the ends of the sections are very near together, so that the straw is not likely to be blown ofi bywind in falling from-one section to the other. By the herein-described mean-s and manner of attachingthe sections tothe adjustable support and the clutch connections itwili be observed that either or both sectionscan be connected or disconnected from the support simply by lifting the end out of the slots, and at the same timeth-eclutch connections between the driving-shafts are automatically engaged or disengaged.

While I have described independent belts on each section, yet one single belt could be employed, running over bothsections. doable belts, however, do away with any need of take-up devices, which might be required if a single belt wereused, and are lesstroublesomein folding or setting up the carrier.

My stacker'may be used asan independent machine or as an attachment to thrashingmachines, the ease with which it can be erected, its compactness when dismantled, and its simplicity rendering itv easily portable.

Having described my invention, what I claim as new, and desire to secure by Letters Patent thereon, is-- 1.. The combination of the supporting-frame having oppositely-opening slots at its sidesadapted to engage shafts on the adjacent ends of conveyor-sections with the said conveyersections, which have their adjoining ends detachably supported on the frame by means of said slots and shafts, substantially as described.

2. 'ihecombi'nation of the supporting-frame, the pair of clutch-blocksmounted at one side thereof, and drive connections between said clutch-blocks with conveyor-sections having their adjoining ends connected to said frame opposite the respective clutch-blocks and having the conveyor-belt shafts adjacent to said ends engaged with said clutch-blocks,

substantially as set forth.

3. The combination of the telescoping frame with the pair of conveyor-sections independ- The ently and removably connected to the upper section of said frame, and the ropes for supporting and adjusting the end of the deliverysection, substantially as described.

4. The combination of the supporting-frame having a pair of shafts at one side driven one from the other and clutch-blocks on the inner ends of said shafts with the conveyorsections removably connected to said frame opposite said shafts, the shafts journaled in the ends of said sections, the conveyor-belts 5 thereon, andthe connections between the adjoining shafts of said sections and the said clutch-blocks, substantially as specified. 5. Thecombinationofthe supporting-frame and thebracket andplate attachedthereto with theconveyer-sections connectedto said frames by shafts en gaging oppositely-facing inclined slots in said bracket and plate, substantially asdescribed.

6. The combination of the telescoping frame, the pair of conveyor-sections independently and removably connected to the extensionsection of said frame, the independent carrier-belts on said sections, and the shaft, clutch-blocks, pulleys, and belts for driving the carrier-belt in one section from the carrier-bel't in the other section, substantially as and for the purpose described.

'7. The combination of the frame having oppositely-opening slots at its sides with the pair of conveyer-sections, the shafts in the adjoining ends thereof adapted to rest in said slots and thus connect the carrier-sections to' the frame, substantially as set forth.

10. The combination of the frame, the-shafts D E, thebracket F, and plate f, slotted, subfstantially as described, opposite said shafts, lwith theconveyer-sections G L and the-shafts f in theends thereof, the shafts at the adjoining fiends of said sections resting in the slots in fsaid bracket and plate, thereby supporting fithesections on the frame, and said shafts being loosely engaged with shafts D E', while the sections are connected to the frame, substantially as described. 11.
